NOTES
1
If the CLKOUT Pin is not used, turn it off using CLKODIS in SPORT0 autobuffer control register.
2
If the interrupt/programmable flag pins are not used, there are two options: Option 1: When these pins are configured as INPUTS at reset and function as interrupts
and input flag pins, pull the pins high (inactive). Option 2: Program the unused pins as OUTPUTS, set them to 1 prior to enabling interrupts, and let pins float.
3
All bidirectional pins have three-stated outputs. When the pin is configured as an output, the output is Hi-Z (high impedance) when inactive.
4
CLKIN, RESET, and PF3:0/MODE D:A are not included in the table because these pins must be used.
5
Hi-Z = High impedance.
